' TYPE-WRITER.

Specification of Letters Patent.

Patented Nov. 28, 1916.

To all ic/wm 1'2 may conccrn:

Be it known that I. ALVAII C. RonnUcK. a citizen of the I nited States.residing at \Yoodstock. in the county of Mcl-Ienry and State ofIllinois. have invented certain new and useful Improvements inType-\Vriters. of which the following is a specification.

This invention relates more particularly to the type-bar guide and themeans for locating the relationship between the carriage or platen andthe printing point of the machine.

The principal object of the invention is to. provide new and improvedmeans for guiding the type-bars to the printing point and for providingimproved facilities for locating the position of the sheet to be printedwith respect to the printing point of the sheet,

For the attainment of these ends and the accomplislunent of other newand useful objects. as will appear. the invention consists in thefeatures of novelty in the con-- struction. combination and arrangementof the several parts generally shown in the accom mnying drawing anddescribed in the specification but more particularly pointed out in theappended claims.

In the accompanying drawing. Figure 1 is a view of a portion of atypewriter illustrating my invention as applied. showing a.

typebar in dotted outline: Fig. 2 is a side view of the same: Fig. I isa top view. and Fig. 4 is an enlarged perspective view of the typebarguide proper.

To provide for a perfect alinement it is necessary not only that the typbar guide proper he possessed of a certain resiliency but also thatmeans he provided for bodily shifting the printing point in alateraldirection. It is also desirable to provide the best possiblemeans fol locating the line of printing when shifting paper in theplaten to match a line already printed or begun, as for example. makingadditions or insertions. The present invention is particularly designedand intended to accomplish these results. I

In the drawing a type-bar segment 6 is shown to which a type-bar guide 7is secured. This type-bar guide comprises a guide proper and is formedwith a peephole 8 preferably circular in form with pointers 9diametrically opposite at the top Supported by the type-writer carriage(not shown) is a platen 10 and a carriage scale 11. The carriage scaleis visible from the front of the machine through the peep-hole 8, thepointers i cooperating with the scale to indicate the position of thecarriage and the platen 10 with respect to the type-bar guide proper.

The type-bar guide proper comprises a notch. 1'2 in the upper edge ofthe type-bar guide 7 of greater width than the width of the type-bars.The type-bar guide ispreferably constructed of a single sheet or pieceof material so that it is stamped from sheet material and formed with aforming die. Extending laterally from the sides of the notch 12 areportions 13 which are bent first substantially at right angles to theplane of the sheet of material and then are rounded in ardly toward eachother forming a curved striking surface l-t'with the extremitiesdisposed in the notch 12. the sides of the ends being substantiallyparallel. spaced from each other and spaced from the sides of the notchto permit a movement of the extremities in either direction in thenotch. These extremities.- however. are of resilient -material and tendto separate at the ends. In order to accurately define the openingbetween the ends. an adjusting screw 15 is provided for each of theoppositely extending portions 13. These screws are threaded through theportion at right angles to the plane of the guide member so that theextremity of the screw bears against the portion at a distance from theend thereof which is in the notch. The object of this is to permit acertain resiliency of the extremities of the guide portions proper andalso to provide means for adjusting them.

With this adjustment it is obvious that the extremities of the portions13 may be adjusted with respect to each other and may also be moved toshift the guiding surface to one side or the other. thus furnishing anadjustment to compensate for any inaccuracies in the manufacture of apart and to make it possible to have the type strike centrally with thesegment 6. In order to hold the adjusting screws 15 in any adjustedposition locknuts 16 are provided.

Secured to the type-bar guide are line finders 17 formed of resilient orflexible ma teriaL'one on each side of the guide proper, the upper edgesof which accurately define the printing line. The position of theprinting point with respect to the printing line is shown more clearlyin Fig. 2, in which a type-bar 18 is shown in dotted outline with one ofits types 19 located on the line defined by the line finders 17, Viththese line finders it is possible to locate the printing line morequickly when shifting paper in the platen to match a line already begun,as for example, when making insertions or additions. This line findercooperates with the peep-hole sight and the carriage scale 11 for moreaccurately and quickly locating the relationship between the platen andthe printing pointof the machine.

3. In a typewriter, a type-bar guide composed of a single piece ofresilient sheet material having a notch in the .upper edge thereof widerthan the type-bar, with portions extending oppositely from the sides ofthe notch adapted to be bent out of the plane of the material and to berounded inwardly with the ends thereof disposed and freely movablelaterally in the notch, the said opposite ends in the notch beingsubstantially parallel and the notch being of sufiicient width to permitthe lateral movement of both of the saidends in the notch.

4. In a typewriter, a type-bar guide comprising a member with a notch inthe upper edge thereof, and resilient members formed as a continuationof the sides of the notch bent outwardly and rounded toward each otherand inwardly with resilient extremi ties substantially parallel, spacedapart and spaced from the sides of the notch, and a single adjustingdevice for'each resilient extremity to vary the position of theextremity in the notch.
